Abstract
Description
- The present invention concerns an over-centre fastener as stated in the preamble of claim 1 and disclosed in US-A-3,831,224.
- Over-centre fasteners (also denominated toggle fasteners or latches) are commonly used for securing - and often clamping - two objects together, such as keeping a lid in a closed position on a box or case. A first part of the fastener, referred to as a striker and often having a hook-like shape, is attached to one of the objects. A base member of the other part of the fastener is attached to the other object.
- There are two different types of over-centre fasteners.
- In a first type (see e.g.: http://www.ojop.com/700.htm), a first end of a lever is jointed to the base member so as to be swingable about a first axis. The other end of the lever serves as a handle member. At a distance from the first end, an engagement means is linked to the lever so as to be swingable about a second axis parallel to the first axis. In use, the engagement means is brought into engagement with the first part of the fastener and the handle with the second axis is swung about the first axis to move the engagement means closer to the base member. In order to vary the distance between the second axis and the engagement means, and thereby the engagement force, the engagement means has a threaded stem member engaged in the threads of an internally threaded body member rotatably connected to the lever about the second axis. The body member is normally a cylindrical body rotatable about its axis.
- In a second type of over-centre fastener (see e.g.: http://www.ojop.com/900.htm), a first end of a link is jointed to the base member so as to be rotatable about a first axis. A second end of the link is jointed to a first end of a handle member. A second end of the handle member is provided with engagement means for engagement with the first part of the fastener. In use, the engagement means is brought into engagement with the first part of the fastener, and the handle member is operated, involving rotation of the second axis about the first one, thereby moving the engagement means closer to the first part. In order to vary the distance between the first and the second axes, the length of the link is variable in that it comprises a threaded stem member engaged in an internally threaded body member connected to the handle and containing the second axis. In this case, the body member is usually formed from folded sheet metal.
- In both types of fasteners, there is a desire to prevent undesired relative rotation of the two threaded members. Such rotation often occurs due to vibrations or other exterior influence in the unlocked and unloaded state of an over-centre fastener, and may result in that a particular setting of the fastener for a particular clamping case may be lost. This, in turn, may result in that clamping becomes too loose or to tight, or, in case such condition is discovered at all, in a time consuming renewed setting.
- Thus, the problem to be solved by the present invention, and that must have existed for at least a century, is to provide a means for retaining undesired relative rotation of the externally threaded stem and the internally threaded body of an over-centre fastener.
- The present invention makes use of what is previously known from various lock nuts, viz., the use of a frictional insert, to an over-centre fastener.
- In practice, this is accomplished by simply using a conventional lock nut as the internally threaded body.
- In the lock nut case, in the second type of fastener, according to the invention there is provided a holder for a nut connected to the handle member to be rotatable about the second axis. The holder is formed from sheet metal to receive the nut in an unrotational manner.
- Embodiments of the present invention will now be described, reference being made to the accompanying drawings, wherein:

- Fig. 16
- is a section taken along line XVI-XVI in Fig. 15; and
- Fig. 17
- is a section taken along line XVII-XVII in Fig. 15.
- The state of art fastener shown in Figs. 1 and 2 is shown to connect and clamp together two
separate pieces first piece 11, and asecond part 14 fixed to thesecond piece 12. The striker has a hook-like free end 13a. The second part comprises abase plate 15 fixed to thesecond piece 12, alever 16 and anengagement member 17. Thelever 16 is swingable aboutrivets brackets base plate 15. Afirst end 17a of theengagement member 17 is threaded and engages internal threads of acylindrical body 19 which is linked to thelever 16 at a distance from therivets cylindrical body 19 is carried between spacedlegs lever 16 so as to be rotational aboutstub shafts 21 engaged in the spaced legs. A free end of theengagement member 17 is formed with aneye 17b engaging the hook-like end 13a of thestriker 13 in the locked position shown in Fig. 1. - In the unclamped state of the engagement member, its threaded end is likely to disengage from the threads of the
body 19 due to, for instance, vibrations. To overcome this risk, the present embodiment shown for illustrative purpose only, proposes to use a conventional lock nut, for instance of the kind having a friction increasing inlay at one end of its internal threads. - Fig. 3 shows how this may be realized in a fastener of the kind shown in Figs. 1 and 2. A
rectangular aperture 22 is machined through the cylindrical body 19' and alock nut 23, having a width between two of itsopposed sides aperture 22, is introduced into the aperture. Thereafter, the threadedend 17a of the engagement member is threaded through the nut and afriction increasing inlay 24 provided at one of its ends. The internal threads of the cylindrical block may be maintained, although it is preferred not to have such threads in this case, since they may interfere with the threads of the nut when mounting the threaded end of the engagement member. - The inventive idea applied to the second type of fastener is shown in Figs. 4 - 6, wherein the same reference numerals are used as in Figs. 1 - 3 for corresponding parts.
- As in the previous embodiment, a
first piece 11 is to be clamped to a second piece 12 (Figs. 4 and 5) by means of a fastener. The fastener is shown in Fig. 4 to be in a partly open state and in Fig. 5 to be closed, having clamped the two pieces together. A striker 13' is attached to thefirst piece 11 and abase plate 15 is attached to thesecond piece 12. Again, the base plate has spacedbrackets cylindrical body 25 is rotatably carried between the brackets by means ofstub shafts stem 27 havingthreads 27a at one end has a reduced diameter opposedend 27b extending through a diametrically extendinghole 28 through thecylindrical body 25. Thestem end 27b is jolted at 29 so as to firmly keep the stem in relation to thehole 28 and the cylindrical body. - A
handle member 30 of inverted U-shaped cross section has spacedflange portions 30a, 30b and a hookedforward end 30c for engagement with the striker 13'. - A bent sheet metal structure 31 has a generally inverted U-shaped portion including
opposed flange portions web portion 31c. The flange portions are linked to arespective flange portion 30a, 30b of thehandle member 30 by means ofrivets web portion 31c carries anintegral extension 33. Afirst portion 33a of the extension is bent at substantially 90° so as to extend along and abut a respective forwardly directededge 34 of theflange portions 30a, 30b. Asecond portion 33b of the extension is bent at 90° in relation to the first portion, and athird portion 33c thereof is further bent at 90° in relation to the second one.Flap portions 33f originally extending in opposite directions from the third portion are bent towards thefirst portion 33a so as to be mutually parallel, thus forming anut retaining pocket 35. The distance between theflap portions 33f is slightly greater than the width betweenopposed surfaces lock nut 23 received within thepocket 35 so as to unrotationally keep the nut therein.Holes portion 27a of thestem 27 are provided in the third andfirst portions extension 33. - It will be realized that in operation of the fastener, the
extension 33, and particularly itsthird portion 33c with itsflap portions 33f, will be exposed to only minor stresses keeping the nut unrotational, whereas the clamping forces will be transferred from thestem 27 through the nut and into thefirst portion 33a of the extension, which abuts theedges 34, thus directing the clamping forces into the opposed flanges of the structure 31. - In the embodiment shown in Figs. 7 and 8 shown for illustrative purpose only, the conventional, internally threaded
body 19 is completed with a friction increasing insert resembling that of a conventional lock nut. - The enlarged section of Fig. 9 more clearly shows a diametrically extending
hole 35 through thebody 19 provided with its internal threads 35'. The hole has a wideneddiameter end portion 35" at one end, and afriction increasing insert 36 is received within that end portion so as to rest against astep 37. The edge of the widened end portion is upset at diametrically opposed locations A, B (Fig. 10) so as to positively keep theinsert 36 in place. Like in a conventional lock nut, the internal diameter of the insert is smaller than the external diameter of the threadedend 17a of theengagement member 17. A preferred material of the insert is Nylon®. - As one alternative to the cylindrical shape of the internally threaded
body 19 it may be advantageous to provide an internally threadedbody 38 having a substantially square cross section as shown in Figs. 12 - 14, or to provide an internally threadedbody 39 having a hexagonal cross sections as shown in Figs. 15 - 17. Such cross sections provide the opportunity to make both ends of thehole 35 in flat opposed surfaces of the respective body. Also, a flat surface enables upsetting the edge of the widened portion of thehole 35 at more than the two diametrically opposed locations A and B shown in Fig. 12, viz. also at diametrically opposed locations C and D.
